SPECIFICATION forming part of Letters Patent No. 548,502, dated October 22, 1895.

Application ld December 20,1894. Serial No. 532,493. (No model.)

To @ZZ whom it may concern:

Be it known that I, CARL BARUS, of Washington, in the District of Columbia, have invented certain new and useful Improvements in Apparatus for Racking or Transferring Carbonized Liquids, of which the'following is a specification, reference being had to the accompanying drawings.

The object of my invention is the produc- Io tion of means whereby liquids charged with gas-as, for instance, carbonized beer-may be transferred from one receptacle to another without appreciable Waste of liquid or gas, and whereby the receiving-receptacle may be r 5 hermetically sealed without incidental waste.

To these ends my invention consists in the novel construction of a bung and socket and of a cock adapted to co-operate therewith to establish an equilibrium of the pressure of gas within the two receptacles, without which the transfer of carbonized liquid is attended by decarbonization or frothing.

Referring to the drawings, in which I have illustrated the preferred form of my appara- 2 5 tus and several modifications of the construction of the bung, Figure I is a view illustrating the application of my device. Fig. II is a central longitudinal section through the cock and bung, showing the parts in the position they assume during the racking of the liquid. Fig. III is a similar view showing the cock closed. Fig. IV is a central longitudinal section through the bung, the cock being shown in elevation and the bung rotated to 3 5 seal the receiving-receptacle. Fig. V is an elevation showing the cock about to be forced into close relation to the bung, the position of the parts when the cock and b'ung are locked securely together being shown in dotted lines. Fig. VI is a sectional view of a modification of my device, and Fig. VII is a view of another modication.

Referring to the gures on the drawings, 1 and 2 indicate closed receptacles-as, for instance, liege-which for convenient designation, I shall term a discharging and a receiving receptacle, respectively. These are preferably placed in different horizontal planes, as illustrated, and it being under- 5o stood that it is desired to transfer carbonized or other gas-charged liquid from the upper to the lower receptacle, I will proceed to describe the special mechanism I employ for effecting the transfer.

3 and 4 indicate the top and bottom of the 55 receiving-receptacle, the former being provided witli a preferably-circular aperture 5 for the reception of the correlatively-shaped head 6 of a cylindrical socket 7, preferably of less diameter than the diameter of the head 6o and depending therefrom into the receptacle 2. The head is provided with an annular flange 8, let into the Vtop 3 to insure a tight joint to prevent the escape of gas; but the expansion or swelling of the Wooden receptacle 6 5 ordinarily sufces for this purpose. The internal walls of the socket preferably converge somewhat from the top to the restricted lower end 9, and are screw-threaded to receive a correlatively-converging externally-threaded 7o hollow bung 10, closed at its lower end, as illustrated. The socket is provided with a gas-vent 1l, preferably immediately below the head, and with somewhat larger ports 12 and 13, connected by a pipe 14, as illustrated. It will be observed that the port 13 is directly below the port 12 and is also below the upper threaded portion of the socket and the bottom of the bung, this arrangement permitting the How of liquid from 'the port 12, through the pipe 14, 8e and into the socket below the bung, for a purpose hereinafter specified, and finally through a depending tube 15, preferably screwed into au aperture 1G in the bottom of the socket and extending to the bottom of the receptacle. In order to prevent clogging, the tube 16 may be cut away at an angle, as indicated at 17.

The hollow bung 10 is designed, as illustrated, to screw into the socket, and is provided, therefore, as before stated, with ex- 9o ternal threads, correlativo with the internal threads of the socket, and with a lateral, preferably hexagonal, flange 1S at its top, adapted to limit its movement and to c-o-operate with bung-actuating mechanism presently to be described. The bung is also provided with a vent 19 and a port 2O properly located, respectively, to register with the vent 11 and the port 2O in the socket when the parts are in the position illustrated in Fig. I, the rota- Ico tion of the bung sealing the receptacle by -removing the vents and ports in the socket and bung out of corelation.

In order to prevent the escape of gas between the threads of the socket and bung, I coat either or both of them with a film of soft metal L-as, for instance, tin or solder-so that when these ports are screwed together and the bung is closed the receptacle will be hermetically sealed.

2l indicates an annular bench surrounding the inner walls of the bung, adapted to receive a flexible washer 22.

23 indicates diametrically-opposite recesses in the under side ofthe flange 1S.

The mechanism thus far described consti? tutes what I will call the sealing7 mechanism, for the reason that these parts co-operatefto hermetically seal the receptacle or to permit of the egress of gas andthe ingress-of liquid, and are not designed to be detached from each other or from the receptacle except for cleaning or repairing. I shall ynow proceed, however, to describe the coupling mechanism, which is ordinarily connected with the discharging receptacle or reservoir-and which is only operatively connected with -thesealing mechanism when it is desired to transfer liquid to the receiving-receptacle.

24 indicates what may be termedan equalizing-cock, its office being to permit the escape of gas into the receiving-receptacle to initially establish an equilibrium between the internal pressures of the two receptacles and to thereafter permit the ingress of liquid into the receiving-receptacle and the escape of gas therefrom into the reservoir, to maintain the equilibrium of pressure during the transfer of the liquid.

25 indicates the cock-casing, provided with a depending bung-tube 26 of a diameter correspondingr with the internal diameter of the bung and adapted to fit closely therein, the annular flange 27 of the casing fitting within the annular bench 2l and compressing the washer 22 to effect an airtight connection between the cock and bung.

The cock-casing proper is provided with a tapering bore 28 for the reception of the correlativelytapered plug 29 and with a bore 30 at right angles thereto, foi'niingacontinuation of the tube 26, and the upwardly-extending pipe connection 3l, which connection is preferably screw-threaded to receive the end of a preferablyflexible pipe 32, connected at its opposite end with the dischinging-receptacle at or nearits bottoni. The plug is provided with a transverse aperture, as usual.

indicatesacomparatively small pipe connection screwed into the small end of the plug and connected with the interior of the recep tacle 2 through curved ducts 34 and 35 in the plug and casing, respectively, and through a small metallic pipe 36, extendingr longitudinally through the tube 26 and communicating at its opposite ends with the duct and with the aperture 37 through the side of the tube 26, which aperture is correlative with the vent 17 in the bung. The duct 34 is provided with an elongated opening 34a for a purpose hereinafter made apparent.

38 indicates a small tube screwed upon the rconnection 33 and communicating at its opposite end with the discharging-receptacle, above the liquid therein.`

Suitable means may be employed for preventing leakage around the plug of the cock and to compensate for wear, the simple device illustrated consisting of a disk 39 of greater diameter than the end of the plugr and secured thereto by screws 40, an intermediate resilient gasket 4l serving to constantly urge the plug into its socket and to constitute a packing. The plug is provided with a suitable handle 42, as usual.

'The sealing and coupling mechanisms described constitute the apparatus :especially designed to successfully accomplish the transfer of the liquid; but much time and labor can be saved by the employment of certain novel mechanism for attaching or detaching the cock to or from the bung and for rotating the bung to open the same when the cock is so attachedorto-close and `seal it when the transfer has Abeen effected and before the cock is removed. To this -end I secure upon the cock-casing by any suitable means a seinicylindrical saddle43,provided upon its opposite sides with depending lugs 44 and apertured at its top for the reception of the `pipe connection 3l. Between the ylugs 44 on either side of the saddle I pivot, as upon rods 45, swinging arms 46, bifurcated ateither end, as indicated, for the reception of diametricallyopposite actuating-levers 47, pivotallymounted upon rods 48and forgravity-pawls 49, pivoted upon the rods and pointed at their lower ends to engage ratchet-teeth 50 upon Vthe levers. The short ends of the levers are designed to engage the recesses 23 in the bunghead.

Springsl or othersuitable mechanism may be employed to assist lgravityin effecting the engagementof the pawls with the levers, and springs 52 may be secured at one end to the saddle and detach-ably fastened to eyelets 53 upon the arms when it is desired to hold the pawls out of engagement with the levers-as, for instance, when removing the cock from the bung.

In the drawings I have illustrated, in addition tothe preferred form of my device cen tain modifications thereof, Fig. VI illustrating as the equivalent of the part 4 a cylindrical connection entirely surrounding the lower end of the socket, into which liquid passes through-the ports l2 and 2O and to which the tube l5 is directly connected instead of to the socket.

Fig'VII shows a modification in which there is no channel for the liquid external of the Socket, the bung being provided witha valve end adapted to seat in the bottom of the socket, the liquid passing through ports im- IIE mediately above the valve and around the same within the socket.

Various modifications of the details of construction shown and described might be made to suit varying conditions, and I desire to reserve to myself the right to make such changes and modifications as may come within the scope of my invention.

The operation of my device is as follows: Supposing the tubes 32 and 38 to be properly connected to the discharging-receptacle, the bung of the receiving-receptacle to be in the opened or unsealed position, and the cock to be closed, the levers are raised and the bungtube of the cock is inserted into the bung. The operator now grasps the handles of the levers and forces them downward, when, as is evident, the cock will be forced closely against and into engagement with the bung, the levers being fulcrumed within the recesses in the bung-head. The parts are securely locked in place by the pawls dropping into engagement with the teeth upon the levers, the aperture 37 and the vent 19 being correlative. The plug of thecock is now turned until communication is established between the two receptacles through the vents l1 and 19, the tube 36, the vents 35 and 34C, and the tube 38, which, by virtue of the elongated openings, will be somewhat in advance ofthe establishment ot' communication between the receptacles through the pipe 32, cock, bung, socket, and tube 17. It will appear then that the gas will now from one receptacle to the other until the pressure Within the receptacles is equalized, when, in accordance with well-known principles, the liquid will tlow freely, the gas dispiaced by the iniiowing liquid escaping into the discharging-receptacle to maintain the equality of pressure. The racking of the desired quantity ot' liquid having been accomplished the cock is closed and the operator swings the levers laterally, turning the bung suiiiciently to remove the vents and ports in the socket and bung out of corelation. By reason of the soft-metal seal between the threads of the bung and socket the receiving receptacle is hermetically sealed. The cock is removed by forcing the levers upward, their short arms being fulcrumed against the head of the socket and the pawls being held out of engagement with the teeth by the spring 52.
